reviews: I must say, I was impressed with the monitor once I got to grips with it. My recommendation is to check out a YouTube Review rather than try to make sense of the slightly baffling instruction manual. Once you do that you will have a reliable-ish (no consumer product is going to give medical standard measurement) heart rate monitor for a fraction of the cost you would expect.
Battery life is good and mine came with 2 straps, a simple but ingenious catch allows you to quickly swap between them, I only wish all watch straps had this feature. The dock makes charging a breeze, although it will not be required everyday which is a big plus also.
Overall I am very happy with the purchase and recommend it to anyone in the market for a heart rate monitor which does not require chest straps.
